Product information

BAER HSSE-TiAlN Machine Tap - 40° RSP - UNF 7/16 x 20 - DIN 376 Stainless Steel

Our machine taps are powerful and reliable taps for efficient machining in one step with the machine. Machine taps are used especially in industrial manufacturing. They can be used in CNC machines, thread cutting machines, cordless drills and pneumatic tapping arms, among others. As they are characterised by high efficiency and low production costs, they are often used in series production. The thread is cut by machine in one operation. Thus, although the BAER machine tap can basically be compared to short machine tap, it is designed for use with the machine.
The screw tap has an overflow shank according to DIN 376. This means that the shank has a smaller diameter than the thread. This means that the screw tap can also be used in deeper holes and longer thread lengths. It can also be used in blind holes, as the short chamfer and the spiral flutes ensure that the chip is discharged backwards out of the hole.
Every material shows individual chip behaviour. Therefore, screw taps must have the correct rake angle and - for even better results - a specially treated surface. This is the only way to achieve a good chip transport and to produce a thread that is true to gauge.
The high quality of the cobalt-alloyed HSSE steel we use ensures that our tools are extremely durable and robust. Due to special hardening processes and repeated tempering the hardness structure is very homogeneous, which forms the ideal basis for a genuine BAER screw taps. This increases the toughness and stability of the screw taps, allowing them to remain in use for longer.
The TiAlN coating is more resistant to friction and heat and therefore offers performance advantages at high temperatures, few cooling options (such as with small dimensions and deep holes) and faster cutting speeds (more than 60 m/min). TiAlN also has advantages when machining poorly machinable and wearable materials and can also be used dry to a limited extent. Recoating of TiAlN tools is possible up to 5 times without removing the old coating

Cutting speed vc [m/min] = (Outer diameter * π * speed) / 1000

Rotation speed n [1/min] = (Cutting speed in m/min * 1000) / (Outer diameter * π)

Feedrate programming [mm/min] = speed * pitch

Please note that the above cutting speeds are indicative and must be adjusted depending on lubrication and actuation.
